The luminescence properties and photophys. mechanism of a spiro-acridine based mol. DBPz-2spAc in toluene and aggregation states is theor. predicted. The solid state can effectively suppress nonradiative energy loss and thus improve luminescence efficiency. Organic LEDs based on DBPz-2spAc show high luminescence efficiency. Studies based on spiro-acridine derivatives indicate that bending the degree of acridine in excited state will directly affect the nonradiative energy loss. The understanding is improved of the luminous behavior of spiro-acridine derivative-based thermally-activated delayed fluorescence (TADF) emitters in solution and in aggregation state, which should pave the way for the design of efficient deep red TADF materials. In the experiment, the researchers used many compounds, for example, Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4Product Details of 105598-27-4).
Dipyrazino[2,3-f:2′,3′-h]quinoxaline-2,3,6,7,10,11-hexacarbonitrile (cas: 105598-27-4) belongs to quinoxaline derivatives. Condensed heterocycles of quinoxalines have become attractive targets in synthetic and medicinal chemistry due to their significant biological activities. Quinoxalines are used as dyes, pharmaceuticals, and antibiotics such as echinomycin, levomycin exhibiting antitumoral properties. Quinoxalines establish also the basis of anthelmintics and receptor antagonists.Product Details of 105598-27-4
